Hi,
it’s due to the BReduce option of B1 being set to True.
Which is probably not a good choice for a default.
In both stable and dev you can use
SetOptions[B1, BReduce -> False]
amp = FVD[k, mu] FAD[{k, m1}, {k + p, m2}]
TID[amp, k, UsePaVeBasis -> True]
In the dev version
OneLoop[k, amp]
should work as well, while in the stable version OneLoop
still reduces everything to B0 and A0, which it actually shouldn’t.
Cheers,
Vladyslav
